Zetec and Type 9 is a popular combo. One thing to keep in mind when making the chassis is that either the gear stick (and the reverse light switch), or the thermostat housing is interfering with the chassis. The solutions are either to use the Raceline Zetec water rail, or make a cutout in the tube that is the rear top of the engine bay (with another tube backing it), or modify the transmission tunnel and shift the engine a bit forward (compromising the gear stick reach).

I think you will find you struggle to reach the gear stick if the engine is to far forward, my seats are on runners and I am able to reach but if your not on runners you have to very careful where you place the gear stick in relation to the seat, if that makes sense

Is there any reason the engine is so far back?
In my CAD model, the engine wasn't that far back?

If you look in my build diary you can just about see them. They are the round tube style ones. Really well made tbh. Also have a few other Zetec bits laying around, flywheels, clutch release bearings, spigot bearings, overhaul deal kit for type 9 box, shortened oil pickup maybe more but would need to dig them out.
